On the choice of APEX for the project of development of database applications

Hello

I intend to develop APPLICATIONS of DATABASE based on the customers requirements and also some standard DATABASE applications on finances, inventory, pay etc. I have a concern about finalization on APEX for standard applications. or m set an additional scope of this application.

-Will most likely use XE or Oracle database standard (in some cases)
-Maximum number of simultaneous users 20.
-Max 300 paintings. Entered maximum would go to 100,000 in some tables of the transaction.
-Max 50 Transaction Forms. Forms of master 100.
-Some complex, matrix, master-detail reports would be required 100.
-Application requires data recovery, storage and reporting. Triggers and procedures will be necessary.

-Max development force 6 pers.
-Planning for standard applications.

Pls let me know your opinion, if I can bet on APEX to:
1 rapid application development
2 maintainability
3 multiple user management
4. treatment volume
5 will be able to manage all the complexity required for database applications.
6. I will not consider Oracle forms (should I?)
7. users want to see the reports in simple old format on the screen and print if necessary.

Your expert opinions and suggestions will be greatly appreciated.

Thank you very much

Hello

OK - I answered your other thread with a few suggestions for you.

There are a number of modules that you can use. I use FireFox with Web Developer and FireBug (which is the most useful tool there is). There are others that allow to control the appearance of the pages definition Apex themselves (for example, you can correct the height of the textareas) but I do not use (it is a tool that is generic and not specific to one for Apex but allows you to override the css style for objects on a page of the site). Web Developer allows css/javascript debugging and FireBug helps with page html structure and style - it also has features that allow you to follow the page how long take to load components (very useful if there is a problem somewhere). There are equivalents for IE - I've used them, but it was some time ago and I don't remember their names.

For my applications, the user just prints the report using the normal printing/archiving on the browser or exports data and formats in Excel. In some cases, of course, there are page elements that shouldn't be included - this is where the page template Print Version is used. I know that some users on here frown using HTML for printing the reports - I'm sure that there are advantages/disadvantages to this, so it depends on how 'professional' reports should be, BI Publisher can therefore worth the expense. There are some freebies available for printing (for example, JasperReports) and there are those who like PLPDF ([http://www.plpdf.com]), which are relatively cheap.

To link a button to a process - this is done by clicking on the button in the parameter "when button pressed" on the process definition. What process does, depends entirely on what you need to do at this time. The process would be PL/SQL, so could do something.

Navigation would depend on what you want to browse. Reports come with different options for pagination - including the first/last, previous/next. Some pages of form wizard generated will also include navigation buttons to move between records - but they can be added manually if necessary (I have a thread somewhere that explains how this can be done using one of the many methods).

For your other questions...

1 - click back to move between page elements is one thing to javascript. Be aware, however, that in a return form is usually used to trigger sending
2 right-alignment - in reports, it is just a setting on a column. For forms, it is style that can be applied on the element or by using css
3 - formatting numbers is done on the column definition in a report. Digital formats can be applied to input fields, but it is more complicated because the formatting must be removed before the digital field can be updated (always feasible, but)
4. "restrictions" - it could mean a number of things. SQL is a CASE statement which allows the conditional discharge. Apex has authorization plans that limit access to pages/Articles. JavaScript and/or SQL may be used to verify the top entries / tiny.

  • Does the Group of Developer SQL database objects

    Noob question

    Can group objects of Developer SQL database (tables, views, etc.) and if so, how?

    Thank you

    To be used in the browser of the object, the objects are currently grouped only by the user (login).
    However, you can:
    1 assign synonyms objects to other users.
    2. in the treenodes of your items, open the context menu, select filter
    3. close to the bottom of the filter dialog box, select include synonyms
    This would give the desired result for all objects in the database without having to use the node of other users .

    For all have them as list or report, theFurryOne already said how.

  • Synaptics touchpad two fingers scrolling does not work in the player to develop modern UI application Windows 8.1

    I have a HP Envy TouchSmart UltraBook 4-1161er. Two fingers to scroll worked well in all modern user interface applications that come with the pre-installed operating system Windows 8.1, but the situation changed after the upgrade to Windows 8.1. Now this excellent and very useful two fingers scrolling does not work in the updated reader application. How to make it work?

    If the problem is in the drivers, maybe, install the drivers the latest may correct this?

    I tried to find the latest drivers for the touchpad Synptics in my ultrabook on the HP website, but it's the same old v16.5.3.3, I already have (published in may 2013). Synatics official site contains a link to the latest touchpad driver pack v17.0.19. Can I install it?

    I would try to install the Windows 8.1 (64-bit) driver Synaptics touchpad available in the download section of your sleekbook web support before using compatibility mode.  If the current driver does not work for you, try the earlier versions available .

    If you have no positive results, then use the compatibility mode (select Windows 8) on all three Windows 8.1 synaptics touchpad drivers, starting with the most recent.

    To use compatibility mode to install the driver just softpaq to the right, click on the file and choose troubleshoot compatibility. Select Windows 8 and run the installer.

    What operating system executes your 11 items first?

    You can have only one project first 11 open both elements. You can save that work and open a new one.

    Cannot open a project file (file project.prel) in another.

    If you have 1 projects and to save its chronology or a part of it to a file for import into the project 2, then

    a. for any chronology, you're going to publish + Share/computer/select a choice of export compatible with your workflow.

    c. for a part of the timeline, you set the gray tabs on the work area bar extend over the area you want to export the second... must do when

    you get to publish + Share/computer/for export, you must have a check mark next to the "hand work area Bar only.

    Then you take the export of 1 project, open the project 2 and import export 1 2.

  • Deployment of the APEX, for commercial purposes

    Dear Experts,

    What are the short-term and long-term benefits and disadvantages of each option from the commercial point of view?

    Best regards

  • Re: specification for parameters of the project and the final delivery of the animations for broadcast HD

    Hi all

    I just finished reading the book of techniques of studio by mark christiansen and I have I have some doubts, maybe, someone working on similar projects can help out me, I hope!

    I live in a PAL country and I especially design and animate the graphics in AE with layers of shape, the illustrator files and psd files. I can work in a proyect for broadcast HD tv and some questions and insecurities had crawled in. I would describe who will be I guess than the workflow:

    1 - setting up the project in AE:

    Captura de pantalla 2014-02-14 a la(s) 14.44.19.png

    of course, the working color space should be consistent between applications. Linearize is important, but I Don t well grasp the concept.

    (2) my master composition:

    Captura de pantalla 2014-02-14 a la(s) 14.51.00.png

    Here, the choice of the frame rate should be 25/50 according to the... ? is just a choice if you work with live images of the hd cameras? apply to animations, graphics?

    And last question, which would be the preferred delivery format and the encoding of the file? I know that there is a wide choice, but if you have a set that s works for you and your customers then i´ll be useful.

    Also. If you have an article, you can recommend where there is an explanation very clear be appreciatted, it seems (to me) the deeper you digg I get more confused.

    Thanks in advance!

    You should check with the diffuser. Either they publicly publish their requirements or that they are in a contract. There is not one size fits all here. The best option for the broadcast work is to make a copy almost without loss or loss of your job as a DI (digital intermediate) and then compress the project specifications accurate diffuser using Adobe Media Encoder or another application specifically designed for video compression for delivery. The only time you ever look like an amateur is when you do not ask the specifications. I regularly get the same images different distributors in 6 different formats.

  • How to delete a picture library "referenced" without deleting the original photos in the application which is used to compensate for my projects?

    I made the mistake of setting up Apple Photos on my Mac Pro using the library option "referenced" (which is where my computer file are not copied in the Photos). However, throughout the year, I started to do the 'projects' in pictures by which I copied some files of original photos in the Photos app. My library is now made up of a mixture of many referenced files and some originals copied into the app.

    Now I did some heavy reorganization and clean up the photos in my computer folder, but obviously none of these changes can be found in the photos referenced in the Photo app.

    My goal now is to started using iCloud Photos but I want to do with a clean slate (i.e. without using one of the current referenced library that I have pictures).

    I have two questions:

    (1) is there a way to Photos to delete ONLY the pictures that are files referenced and not the originals that are copied into the app?

    (2) if the above is not possible, then what happens to my projects if I simply delete all the photos I have in the app? I'll always be able to see the photos of the calendar, that I did for example?

    I'm afraid that if I delete my entire library I will not be able to access my projects more in the future. Does anyone have any suggestions on how I can manage this?

    Thank you very much.

    A

    You can consolidate all of the photos that are referenced. If you have used photos referenced in the projects (calendars, books), select the photo in your photo library and use the command "file > consolidate."  This will copy the original referenced in your photo library.

    To find all the files referenced requiring consolidation of create a smart album:

    File > new Smart Album

    Set the constraint for the album 'Photo is referenced.

    Now you have all the photo referenced in an album. You can select the photos in this album and either use ' file > consolidate "to copy in the library or press the ⌘⌫ key combination to delete the picture from the library.

    Before you consolidate or remove a photo referenced, using ' file > reveal in Finder ' to view the original file.  This way you can remove the copy on your disk after you have removed the photo from your photo library.  If the referenced file is left behind, pictures will not remove.

    If you want to use your photo library with iCloud photo library, it is essential to consolidate the pictures referenced, because referenced photos cannot download on iCloud photo library.

  • using the cfg recorded vi analyzer for another project file

    If you open your .cfg in Notepad, you see a reference to your other project or file path?  If so, this is the token that must be modified to be associated with a different project.  I suggest to make a copy of your file and record a new to work with your new project.

  • publish the new class for other projects in a workspace

    HI, I have a workspace, which contains 4 different projects.

    I package all the project under the same path as the package com.xxx.app.version1;

    I made a new class, say DataStruct, it will be used in several projects.

    If I only set the DataStruct in a project, how the other projects can reference this class?

    I do not put the same class file in each project, because it causes problems of consistency.

    Thank you

    Jerry

    solved.

    My own solution:

    Add a new project name xxlib in this workspace.

    Add all the classes newly defined in this project. Pack them as com.xxx.lib;

    first build the jar of this xxxlib. then add this jar file into other projects that are in need of new classes.

    (for each project, the properties-> build-> add jar)

    in the project files that are in need of the new class, add "import com.xxx.lib;"

    Hello friends,

    I developed a small application for playbook. I want to send an email, use adoble flash builder burrito, there is no built-in functions available to send emails in flex 4.5, it can be achieved throug php, cold fusion, or asp.net. I don't know how do it, can someone send me the example to send an email to the project mobile flex.

    Thank you...

    There is no native email client in "flex". PB is not currently an API to use any "native" or "bridged" or by e-mail. If you just want to open the current, the default e-mail client, you can use navigateToURL with 'mailto' as url, or you can send the information to your own server, which can in turn SMTP information. Otherwise, you will need to write your own.
